  1. Oct 23, 2011 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    a=[r''-r0'^2]er+[r0'' + 2r'0']e0 where 0 = theta


    3. The attempt at a solution
    stumped about it, i've tried setting the above to 0 then work out r which is 200 m but that's just cluelessly subbing values into the equation, any directions as to where to head? thanks!

    The car moves along the road with constant velocity v. Find x as function of time. Find how θ and [itex]\dot {\theta}[/itex] are related to v and time.
